Bi-directional communication means two-way communication.
The earliest printers only received data, and they printed out what they were instructed to print.
But if the printer had a problem, like it was out of paper, the computer wouldn't know and keep sending data to print, losing the print job.
So later printers had signals going back to the computer for things like "Off-line" and "Out of paper".
Nowadays, printers communicate all sorts of things back to the computer, such as the level of toner left, the number of pages the drum has printed, and other useful information.
Without bi-directional communications, printers would be a lot less useful!Source(s): (Did you mean to put this in the Printer category?)
